The messier objects as a tool in teaching astronomy  [PDF]
Jesus Rodrigo F. Torres
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.53044
Abstract:

The French astronomer Charles Messier (1730- 1817) compiled a catalogue [1] of astronomical objects which reached109 innumber after additions by later astronomers were added. The catalogue contains galaxies, emission nebulae, a supernova remnant, a double star, globular clusters, open clusters, an asterism, a star cloud, and planetary nebulae. While the objective of Messier in compiling the catalogue was to guide comet hunters not to be confused by his objects which he thought looked like comets [2], the Messier Catalogue as it later became known became a standard guide to astronomers for a study of the sky’s “greatest hits” or the best samples of objects which can be observed and studied. This paper explores the value of the Messier Catalogue in the teaching of Astronomy and Earth Science. The range of objects is wide and contains some of the best examples of their type. The teaching method I propose is the actual observations of the objects through a telescope, with the corresponding explanation. Some principles which will be covered through this process are stellar evolution from the birth and death of stars, galaxy types, formation of galaxies, galactic interactions, life in the Universe, cosmology, and our place in the Universe.

An Option Pricing Analysis of Exotic Bonus Certificates—The Case of Bonus Certificates PLUS  [PDF]
Rodrigo Hernandez, Pu Liu
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.45044
Abstract:

In this paper we introduce a new financial product named Bonus Certificates PLUS and we provide detailed descriptions of the product specifications. We show that the payoff of a Bonus Certificates PLUS can be duplicated by the combination of a long position in the underlying asset, a short position on zero coupon bonds, a long position in down-and-out call options on the underlying asset, a long position in down-and-in call options on the underlying asset, and a long position in the down-and-out put options. We develop a pricing formula to price the certificates. A sample of ten Bonus Certificates PLUS outstanding on December 2007 is presented as an example to examine how well the model fits empirical data. The profitability in the primary market is examined and the results show that issuing Bonus Certificates PLUS is a profitable business. The results are in line with previous studies pricing other structured products. Finally, we simulate and present the sensitivities of the certificates to changes in different pricing inputs.

Rodrigo Hernandez, Yinying Shao
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.45045
Abstract:

This paper introduces a new financial product named Certificates on a Straddle with Forward Start and provides detailed descriptions of the product specifications. It shows that the payoff of a Certificate on a Straddle with Forward Start can be duplicated by the combination of long positions in call and put options on the underlying asset. A pricing formula is developed to price the certificates. A certificate issued by Credit Suisse is presented as an example to examine how well the model fits empirical data. The results show that issuing Certificates on a Straddle with Forward Start is a profitable business and the results are in line with previous studies pricing other structured products.

La Iglesia y la universalidad de la salvación en el cristianismo
Polanco,Rodrigo;
Teología y vida , 2003, DOI: 10.4067/S0049-34492003000400005
Abstract: the present article is a reflection about the universality of the salvation in the christianity. it begins defining the salvation as men's communion with god and among men, with the meaning of plenitude for mankind. then, it refers to christ as the only mediator between god and mankind, because it is god himself incarnated as a man, insuperable plenitude of the revelation. this salvation, because of its characteristics of definite and absolute, becomes eschatological and universal. on the other hand, if the whole mankind has been transformed (=sanctified) for the coming of christ, it is called at the same time to receive conscious and freely this universal salvation. it is the god's kingdom that has broken into earth. then, the article studies the role of the church in this universal salvation: as of incarnation, that has done the concrete way of salvation, the church has established as sacrament, that means, the universal sign and instrument of salvation. it is the presence of christ in the everlasting history of salvation. the church, although is a little flock, at the same time it is the safe germ of salvation, because it is, at the same time, sacrament of god's kingdom, sacrament of christ dead and resurrected, sacrament of holy spirit and eschatological reality. afterwards, the author reflects on the fact of the sacramental characteristic of the church: the "ecclesial" (ie. the formal and established organization) belongs to the essence of the relation of man with god, and the symbolic-sacramental belongs to the essence of human communication. that is the reason, the word, in the incarnation, has assumed the human reality and has become the father's sacraments, and the church has come about the sacrament of christ. god himself gives himself as such, in the finite sign and sinner that the church is. the article finishes with the topic of necessity of the church. as sacrament of christ, the church is necessary to the salvation as soon as objectivization of the wi

El Estado Ausente: la paradójica configuración balnearia del Gran Valparaíso (1850-1925)
Booth,Rodrigo;
EURE (Santiago) , 2002, DOI: 10.4067/S0250-71612002008300007
Abstract: since the second half of the 19th century, the state?s marked preference for the industrialization of the coast of valparaíso caused the dislodging of the first sea resorts in the bay. at the same time, private investors had settled their sea resorts in the recently created village of vi?a del mar. however, their investment was not able to modify vi?a?s paradoxical condition of an inland-facing village until the early 20th century. this contradictory condition is explained by the lack of state interest in the promotion of hedonistic uses of chile?s central coast. only the combined action of both public and private intervention permitted a progressive re-orientation of vi?a del mar towards the coast. this was decisive in establishing its future configuration as a city centered on tourism around sea resorts.
